Default Bogging at highway speeds

My 94 ranger 2.3 xlt is hesitating and boggin around 55 to 70 mph if I have it wide open it it runs fine but if I'm going up a slight hill at 55 it will loose power then pick up after a little. I've put new fuel filter a regulator. Also put new plugs and wires .I'm just dumping money it and and I can't figure out why its doing it if any one has any clue to why its doing this give me a shout

My 94 2.3 did the same with a stick...loosing power up hills and I couldn't afford to dump it back then.

How's your truck set up, any power draining mods...big wheels on an older trans, funky intake and maf,
what was the condition of the old plugs and what brand plugs did you replace with. What is your current mpg
Hope you find the cause and not go spending $$$.

Just a clue but iirc to pass inspections, took the opportunity to straighten out the exhaust, put on new cats and o2s.
Not embarrassing going up hills after that. This was 5yrs ago and still going strong as a shop truck.

Is it a manual or automatic? Should you be downshifting the manual to 4th gear from OD?

You could do a pressure/volume check of fuel delivery to know that you are getting adequate fuel supply and the pressure is being maintained for proper injector function.

If it seems to lose power as you demand more, and starts to huff and puff, as in not run smoothly, more symptoms of fuel lack. If it runs smooth, but just doesn't have the power, downshift may be proper.
From my travels, TN is all hills anyway, so how would you know flat terrain travel.
Just Kidding!!! I like TN, it is beautiful country.
Is it possible you have blocked converters or partial that are slowing exhaust and limiting power? Removing the upstream O2 sensor, blocking any exhaust from damaging the underside, and test for more power would give you an idea, but I would not do that until other things are exhausted.

Mine is a manual and would do the same thing on hills if I picked the wrong gear. It's 119HP, what do you expect?? An older year like yours is probably even less HP than mine.

I replaced my fuel filter and it helped a lot of the sluggishness up big hills, so if I pick the right gear, at least I can somewhat maintain my speed.

To the wheels a kind estimate would be 85 horsepower for a 94, having an automatic is like the fat kid with asthma running the mile and having a manual is like the other fat kid in gym class running the mile.
